ATTACHIMENT FOR CORN-SHELLERS.

Specification of Letters Patent. Application led December 23,

Patented April 14, 1908. 1907. S'erial No. 407,660.

To all whom it mag/concern.'

Be it known that I, GEORGE B. NELSON, a citizen of the United States, residing at Redfield,.in the county of Dallas and State of Iowa, have invented a new and useful Attachment for Oorn-Shellers, of which the following is a specification.

My invention relates to that class of corn shellers in which a feeder conveyer is detachably connected with the corn Sheller for the pur ose of carrying corn on the cob to the she ling mechanism, and a swinging adjustable conveyer frame is provided for carrying corn cobs from the machine to a wagon o1j` other point of discharge. when it is desired to transport the machine from one place to another, a separate vehicle is rovided for carrying these conveyers.

y object is to provide supporting devices at one side of the Sheller frame designed to receive both of said conveyers, so that they may be carried on the same truck as the ma- In some instances,

` chine,land not in any way interfere with the transportation of the machine. In this connection, I have found that supports that project far enough from the machine frame to support these conveyors may in some instances be objectionable, and may prevent the machine from passin through narrow gateways, and a further o ject is to provide supports so arranged that they may be withdrawn from their rojecting positions in cases where it would be objectionable to have tlplem project out from the side of the mac me.

A further object is to provide means for` supporting the swinglng corn cob conveyer rame in any desired position of its adjustment, so that it will not be affected by the wind or be swung laterally fromother causes when it'has been set to its desired position.

My invention consists in the construction, arrangement and combination with a corn Sheller, of the devices for supporting the oonveyer frames, and thel device for holding the corn co'b conveyer frame in a fixed position, whereby the objects contem lated are attained, as hereinaftermore fiilly set forth, pointed out in my claims and illustrated in the accompanying drawings, in which- Figure 1 shows a perspective view of a i corn sheller with the attachments embodying my invention applied thereto. 2 shows a side elevationof a portion of the rear end of a sheller frame, and a portion of the stationary feeder conveyer frame, and the adjustable feeder conveyer frame operatively connected with the main stationary feeder conveyer frame. Fig. 3 shows a detail view partly in section illustrating the forward conveyer frame support in its withdrawn position.` Fig. 4 shows a detail perspective view of the forward conveyer frame support detached. Fig. 5 shows a detail perspective view of a portion of the guiding brace for the forward support. Fig. 6 shows a detail sectiohalview illustratin the detachable feeder conveyer frame and tie delivering conveyer frame resting in the rear support. Fig. 7 shows an enlarged detail view partly in section of the arm for guiding the rope that supports the delivering conveyer to illustrate the means for clamping said arm to its supporting plate, and-Fig. 8 shows a detail perspective view of the plate for supporting the arm that guides the rope of the delivering conveyer.

Referrinfr to the accompanyinv drawings, l have used the reference numeral 10 to indicate the body of the Sheller. This body is mounted upon a rear axle 11 having a supporting wheel 12 at each end.

13 indicates a bolster mounted on the rear axle and formin part of the machine frame.

14 indicates t e forward aXle swiveled to the frame and having the supporting wheel 15 at each end. Above it 1s a bolster 16 forming part of the frame. longitudinal side pieces 17 of the machine frame that are connected to the forward and rear bolsters, and near their forward ends these side ieces 17 are connected by means of a cross eam 18 which is preferably of T hape in cross section, as clearly shown in ig. 5- i The forward support for the conveyer frames comprises a straight body portion 19 .having an upward extension 20 on its outer end, and having two o positely disposed hooks 21 on its inner endg, which hooks are designed to overla the flanges of the cross beam 18 and be slidingly connected therewith. vThe said body ortion 19 projects through a slot in one o the side pieces 17 thus providing a su port that may be readily and easily movedp to position contained alside pieces-17, to a position extended outwardly from the side ieces'17 far enough to receive the conveyer fi'ames to be hereinafter described. Said support obviously will be firmly held in a horizontal Vposition when at any point of its adjustment.

Mounted upon the rear end of one of the side pieces 17 is an upright 22 havin(T a forked top, and mounted upon the rear bolster 13 is a lug 23 having an opening therein. The rear support comprises a straight body portion 24 having at its inner end a lateral eX- tension 25, having its end projected through an opening in the lug 23 and detachably held therein by a cotter pin 26.

At the outer end of the body portion 24 is a downward extension 27, a horizontal eX- tension 28, and an upward extension 29. The space between the parts 27 and 29 being wide 'enough to admit the conveyer frames lljereinafter described, is clearly illustrated in When it is desired to remove the rear support, the operator simply withdraws the cotterpin 26, then slides the support outwardly until it is disengaged from the lug 23, whereupon it may be bodily removed. When said support is in position for use, the part that receives the conveyer 'frames projects out beyond the rear wheel 12 so that the conveyer frames will not in any way interfere with the movement of the machine.

The stationary feeder conveyer comprises a conveyer frame 30. The structure of this conveyer frame forms no part of my invention, and therefore is not herein specifically` shown or described. This conveyer frame is permanently connected with the receiving end of the corn sheller and projects downwardly and rearwardly therefrom a short distance.

The detachable feeder conveyer comprises a frame 31 with a conveyer 32 therein. It is detachably supported upon the brackets 33 yat the rear of the frame 30, and the conveyer therein is driven by means of the s rocket gearing 33a, which is connected to tie conveyer of the frame 30. It is this feeder frame 31 that is-in some instances carried on a supporting truck when the machine is transported, and the supports before described are for the urpose of holding this frame and also the de ivering conveyer frame when the machine is being transported.

At the forward end of the machine frame is the delivering conveyer frame 34 which isv of the ordinary construction and is detachably connected, and capable of both lateral and up and down movement. The structure of this conveyer itself, and the means for attaching it to the corn sheller form no part of my present invention, and are not herein speciiically shown or described. This delivering conveyer frame is of such size and shape that it may rest within the feeder conveyer frame 30 when the latter is su ported at the side of the frame, as shownin lipig. 6.

In order tovadjustably hold the delivering conveyer frame in any position of its adjustment laterally, I have provided a hemispherical plate 35 designed to be pivoted to the pulley supporting frame 36.

Pivotally connected to the plate 35 is an arm 37 having at its outer end an eye 3S through which the rope 39 that supports the outer end of the delivering conveyer frame is passed. This rope passes over the pulley 40 at the top of the frame 36. Connected with the under side of the frame 37 is a clamping member 41 with its rear end projected under the plate 35. Extended through the clamping member 41 and seated in the arm 37 is a set screw 42 whereby the clamping member 41 may be made to firmly engage the under surface of the plate 35 and thus hold the arm 37 in any position of its adjustment laterally.

In practical use, and assuming that it is desired to transport the machine, l first move the support 19 to its lextended position as shown in Fig. 1, and then place the rear support in the position shown in Fig. 1. I then detach the feeder conveyer frame 31 from the brackets 33 and place it in the supports at the side of the machine frame. then detach the delivering conveyer frame 34 and place it within the frame 31 as shown in Fig. 6. Then the machine may be transported as an ordinary wagon. In. the event that it is desired to pass through a gate-way o1' other place too narrow to admit the machine with the frames at the side thereof, I first remove the frames from the supports then slide the forward support to position under the machine and remove the rear support. By means of the arm 37, the delivering conveyer frame maybe placed in any desired position of its adjustment, and there firmly held so that it will not swing laterally by wind pressure or from other causes, and yet it may readily and quickly be adjusted when desired. j

Having thus described my invention, what I claim and desire to secure by Letters Patent, is-

1. 1n a machine of the class described, an adjustable support capable in one position of supporting a conveyer frame at one side of the machine frame, and also capable of being withdrawn from its projected position, an a second support connected with the machine frame to co-act with the aforesaid support in holding the conveyer frame.

2.
